Buck regulator for automotive and industrial rails
The Maxim MAX16907RAUE/V+ is a 3A step-down (buck) switching regulator rated for automotive environments per AEC-Q100. It accepts an input from 3.5V up to 36V and delivers a positive adjustable output from 1V to 10V, with a fixed 5V option available.
What the ratings mean for your BOM
The 3.5V minimum input lets this part run directly off a cold-crank 12V battery or a regulated 5V intermediate bus. The 36V maximum covers load-dump transients on a 24V truck system without needing an external clamp.
Lifecycle and sourcing
The MAX16907RAUE/V+ is listed as Active with ROHS3 compliance. For dual-sourcing or a second-source option, there is no official cross-reference listed — the Maxim family of automotive buck converters uses different pinouts and compensation, so a drop-in alternate is not available without a board spin.
